This read-write value contains the actual status of the Analog I/O. When reading this value, it will typically correspond to the current status of the Analog I/O. For outputs, writing a value to this OID will cause the output to change to match that value. For inputs, writing to this value will have no effect. It should be noted that many Analog I/O modules will require additional math before the value is usable. For some modules, the value is in tenths or hundredths of the expected unit (for instance voltage might be read as 240 or 2400 for 24 volts)
